The objective of this study is to optimize a novel, audio-recorded physical activity
intervention that is scalable. Using principles of the Multiphase Optimization Strategy
(MOST) framework, a full factorial study will test the unique and combined effects of
different intervention components to identify which combination of components is optimal
for increasing physical activity and mechanisms by which the components are or are not
effective. This information will inform decisions about an optimal intervention package
that is effective, efficient, and minimizes participant burden.

Eligible participants who provide informed consent will be enrolled in a 6-week study. At
the baseline session, participants will be randomized to listen to a brief
audio-recording of different guided thinking tasks. The audio-recordings are based on
combinations of four different intervention components that will be tested in a 2
(positive affect imagery vs. neutral) x 2 (episodic future thinking vs. recent thinking)
x 2 (action planning: yes, no) x 2 (dose: high vs. low) factorial trial. Participants
will also complete a 30-minute brisk walking session on a treadmill. Participants will
return for weekly visits in which they again listen to their assigned audio-recording and
complete a 30-minute brisk walking session.
